Aaaaaand it's fixed! You should no longer see a "video unavailable" message on some recently uploaded videos. Thanks for sticking with us as we figured it out!https://twitter.com/TeamYouTube/status/1116363608114462725 …
Sorry to hear that you've been waiting so long. Looks like your channel is still in review because we couldn't come to a clear decision during initial review. We're reviewing as many as humanly possible. Hopefully you hear back soon. Appreciate your continued patience.
